This guy hitched a ride on some live rock. He just recently started getting getting light, thanks to some rearranging. Im not quite sure what it is but it has grown in size it is now about a quarter inch wide. Any help would be great. View attachment 292546

Looks like a teeny tiny chunk of sarcophyton leather to me. (toadstool) Nice color too!
